Genomic and Transcriptomic Analysis of Pea ( L.) Breeding Line 'Triumph' with High Symbiotic Responsivity.

Pea ( L.), like most legumes, forms mutualistic symbioses with nodule bacteria and arbuscular mycorrhizal (AM) fungi. The positive effect of inoculation is partially determined by the plant genotype; thus, pea varieties with high and low symbiotic responsivity have been described, but the molecular genetic basis of this trait remains unknown.

Identification and Expression Analysis of the Family in L.

The (CEP) peptides play crucial roles in plant growth and response to environmental factors. These peptides were characterized as positive regulators of symbiotic nodule development in legume plants. However, little is known about the CEP peptide family in pea.

A variable gene family encoding nodule-specific cysteine-rich peptides in pea ( L.).

Various legume plants form root nodules in which symbiotic bacteria (rhizobia) fix atmospheric nitrogen after differentiation into a symbiotic form named bacteroids. In some legume species, bacteroid differentiation is promoted by defensin-like nodule-specific cysteine-rich (NCR) peptides. NCR peptides have best been studied in the model legume Gaertn.

Draft Genome Sequence of Rhizobium ruizarguesonis (Rhizobium leguminosarum) Strain 1TK341.

Rhizobium ruizarguesonis (Rhizobium leguminosarum) strain 1TK341 was isolated from pink nodules of fixation-negative mutant line P61 of pea (Pisum sativum L.) grown in soil. Here, we report the draft genome sequence of the strain.

War and Peas: Molecular Bases of Resistance to Powdery Mildew in Pea ( L.) and Other Legumes.

Grain legumes, or pulses, have many beneficial properties that make them potentially attractive to agriculture. However, the large-scale cultivation of legumes faces a number of difficulties, in particular the vulnerability of the currently available cultivars to various diseases that significantly impair yields and seed quality. One of the most dangerous legume pathogens is powdery mildew (a common name for parasitic fungi of the order Erisyphales).

DNA Methylation Patterns Differ between Free-Living RCAM1026 and Bacteroids Formed in Symbiosis with Pea ( L.).

() is a common name for several genospecies of rhizobia able to form nitrogen-fixing nodules on the roots of pea ( L.) while undergoing terminal differentiation into a symbiotic form called bacteroids. In this work, we used Oxford Nanopore sequencing to analyze the genome methylation states of the free-living and differentiated forms of the strain RCAM1026.

Towards Understanding Afghanistan Pea Symbiotic Phenotype Through the Molecular Modeling of the Interaction Between LykX-Sym10 Receptor Heterodimer and Nod Factors.

The difference in symbiotic specificity between peas of Afghanistan and European phenotypes was investigated using molecular modeling. Considering segregating amino acid polymorphism, we examined interactions of pea LykX-Sym10 receptor heterodimers with four forms of Nodulation factor (NF) that varied in natural decorations (acetylation and length of the glucosamine chain). First, we showed the stability of the LykX-Sym10 dimer during molecular dynamics (MD) in solvent and in the presence of a membrane.

Complete Genome Sequence of an Efficient Rhizobium leguminosarum bv. viciae Strain, A1.

strain A1 is used in inoculation experiments with a wide range of pea ( L.) lines. In this study, we report the genome sequence of strain A1, consisting of a 5.

New sources of allele in the pea ( L.) carry the unique variant of candidate LysM-RLK gene .

At the onset of legume-rhizobial symbiosis, the mutual recognition of partners occurs based on a complicated interaction between signal molecules and receptors. Bacterial signal molecules named Nod factors ("nodulation factors") are perceived by the plant LysM-containing receptor-like kinases (LysM-RLKs) that recognize details of its structure (i.e.

Selection Signatures in the First Exon of Paralogous Receptor Kinase Genes from the Region of the L. Genome.

During the initial step of the symbiosis between legumes (Fabaceae) and nitrogen-fixing bacteria (rhizobia), the bacterial signal molecule known as the Nod factor (nodulation factor) is recognized by plant LysM motif-containing receptor-like kinases (LysM-RLKs). The fifth chromosome of barrel medic ( Gaertn.) contains a cluster of paralogous LysM-RLK genes, one of which is known to participate in symbiosis.

Pea Marker Database (PMD) - A new online database combining known pea (Pisum sativum L.) gene-based markers.

Pea (Pisum sativum L.) is the oldest model object of plant genetics and one of the most agriculturally important legumes in the world. Since the pea genome has not been sequenced yet, identification of genes responsible for mutant phenotypes or desirable agricultural traits is usually performed via genetic mapping followed by candidate gene search.
